Wanted my Dolby Surround replace 5.1 system (1000, 2006), because I never use it and it in music playback just too bad sounds and a bunch of cables and devices draws with itself. The Philips DS9800W will fit very well into the living room and are alla Airplay control so no annoying device further in the room. Strategy is to have no DVD player, no Videoaufzeichungsgeräte, no radios and amplifiers, etc. lying around more. TV via Apple connected TV3, Radio and Sound by Philips DS9800W (iPad, iPhone, Mac) video recording on the Internet via Save.TV and any other electronic waste is more notwenig in the room. That works fine. Disadvantages: The status LEDs are mounted on the rear of the boxes, thus it is not clear whether the boxes are activated. No optical input as usual at Apple, for example, common kompinierter jack / Toslink input. My TV has, unfortunately, only an optical output is now not necessary. Pity! But the sound is more than neat for this device class. The build quality is super. Can you therefore recommend. Please note that most LCD TV does not have stereo cable output more! With strong radio network utilization (2.4 GHz range and multi-family house) may lead to trouble! Then you have the radio channels of the router to play until it is stable! This issue is not imputable to the Philips comes towards all wireless models! WLAN N would be nice in the 5 GHz range because there the connection is stable. This could change Philips times, sure kostest only pennies a minute! At the moment, for 660 it is a strong buy recommendation!
